Subject Re: How to list all dynamic fields of a document using solrj?
Date Tue, 30 Aug 2011 06:11:54 GMT
Hi Juan

I tried with the following code first:

final SolrQuery allDocumentsQuery = new  SolrQuery();
allDocumentsQuery.setQuery("id:" + myId);
allDocumentsQuery.setFields("*");
allDocumentsQuery.setRows(1);
QueryResponse response = solr.query(allDocumentsQuery, METHOD.POST);


With this, only non-dynamic fields are returned.
Then I wrote the following helper method:

 private Set<String> getDynamicFields() throws SolrServerException, IOException {
        final LukeRequest luke = new LukeRequest();
        luke.setShowSchema(false);
        final LukeResponse process = luke.process(solr);
        final Map<String, FieldInfo> fieldInfo = process.getFieldInfo();
        final Set<String> dynamicFields = new HashSet<String>();
        for (final String key : fieldInfo.keySet()) {
            if (key.endsWith("_string") || (key.endsWith("_dateTime"))) {
                dynamicFields.add(key);
            }
        }
        return dynamicFields;
    }

where as _string and _dateTime are the suffixes of my dynamic fields.
This one returns really all stored fields of the document:

final Set<String> dynamicFields = getDynamicFields();
final SolrQuery allDocumentsQuery = new  SolrQuery();
allDocumentsQuery.setQuery("uri:" + myId);
allDocumentsQuery.setFields("*");
for (final String df : dynamicFields) {
    allDocumentsQuery.addField(df);
}
        
allDocumentsQuery.setRows(1);
QueryResponse response = solr.query(allDocumentsQuery, METHOD.POST);

Is there a more elegant way to do this? We are using solrj 3.1.0 and solr 3.1.0.

Regards
Michael

Hi Michael,

It's supposed to work. Can we see a snippet of the code you're using to
retrieve the fields?
